Transmission of large volumes of image data via limited spectrum/ bandwidth is a challenge, therefore data needs to be compressed at the transmission end and expanded at the receiver. This compression and expansion may lead to distortion which will hinder the smooth operation of the system. With wireless communication the situation becomes even worse due to noise while traversing. Random bit error or packet losses introduced by the channel may corrupt the critical information. Reliable Transmission refers to error free transmission. In this w o r k an effort has been made to study the factors influencing reliable transmission of medical images via wireless networks and possible solutions to overcome the challenges. Reliability of data transmission over wireless channels can be increased by using channel coding before transmission. 1/2 TC and 3/4 LDPC can be used in case of lower compression ratio and 1/3 TC and 2/3 LDPC codes can be used in case the image is compressed at higher CR.
